1 Introduction

The report discusses the management plan for mitigation of adverse environmental

impacts and increases the beneficial impacts due to mining of Building Stone & Road

Metal

The environmental impacts can be categorized as either primary or secondary. Primary

impacts are those, which are attributable directly to the project, secondary impacts are

those, which are indirectly induced and typically include the associated investment and

changed pattern of social and economic activities by the proposed action.

The objective of preparing environment management plan is to define effective measures

to control and to mitigate the environmental pollution. This report presents the

environment management plan, detailing the environmentally sound technology and the

measures needed to mitigate the anticipated environmental impacts due to the project.

4 Environmental Management Plan

Mining of Road metal involves using heavy machinery and impacts the surrounding

environment. In order to reduce the impact, we assessed the possible impacts on

surrounding environment and suggested possible preventive measures by categorizing as

Air, Noise and Water. The details of the possible causes and measures taken to reduce

them are as follows. In addition to these measures a green belt will also be developed to

remedy the biomass loss occurring due to the mining process.

4.1 Air pollution management

In the process of mining heavy machinery such as excavators, Tippers,etc are used. These

result in air pollution at various stages, which are stated as follows

1. Particulate matter generation from the mining process,

2. Particulate matter generation due to hauling, loading & unloading of mined road

metal

3. NOx & Sox generation form the consumption of fossil fuels in heavy machinery

and transportation vehicles.

4.1.1 Measures taken to reduce pollution

During mining: Particulate matter generation during mining is mainly from drilling holes

which can be controlled by covering the drill holes with cloth.

Transportation:

a. To minimize the particulate mixing in air during hauling the vehicles are never

overloaded and covered with a tarpal

b. The particulate generation from the vehicular movement is suppressed by

sprinkling water twice a day and conducting regular road repairs

Additionally the proposed green belt would act as sinks for particulate matter.

7

4.2 Noise Pollution management

The major source of noise pollution is due to

i. Drilling,

ii. Blasting and

iii. Vehicular movements.

Regular maintenance of noise generating units (repairing, greasing and minimiztion

vibrations) will be taken to minimize noise levels. During blasting operations the noise

level may increase (short time exposures). Blasting will be carried out during daytime to

avoid noise intensity to the surrounding people at night time.

Personal protective equipment like earplugs and other protective devices will be provided

to workers those who are working near by the noise generating sources (drill machine

operators). But as with distance away from the mining operations, the noise levels will

reduce and the anticipated noise levels falls below the day and night residential standard

limits set by CPCB (day Leq 55 and night Leq 45 dB(A)).

Dense vegetation is planned at the periphery of the lease area to minimize the impact of

blasting in the surrounding environment.

4.3 Water Pollution Management

The ground water table in this belt is 24-30 m below from the surface and since the

quarry depth will not reach up to this depth in the near future flooding by ground water is

not anticipated. However, during rainy months, there is a possibility of wet conditions

developing in the working pit. This will be minimized if not altogether eliminated by

adopting simple techniques like digging trenches all round to drain off rainwater and

preventing surface run off from entering and flooding working pit. The water from the

will be pumped by deploying suitable pumps, if and when required, the mine drainage

can be effectively managed and the pit kept dry to keep up the production schedule.

4.4 Green belt development

The whole area is occupied by scattered sparse vegetation of thorny trees and small

bushes. In the quarry lease area no wild animals are witnessed as per the statements

8

collected from the local population, since 50 years. There will be loss of biomass due to

clearing of existing vegetation, but will be compensated by the given afforestation plan.

As the site is near to human settlement other than domestic animals no important wild life

is found that need to take special attention. However due to planned development of

green belt, the area attracts more avifauna and also gives shelter to other domestic

animals.

AFFORESTATION

Every year 81 saplings consists of Neem, Mango, Teak, Baadam and etc. at 3m

interval.

A thorny fence shall be provided to guard the trees from the cows and goats.

The shelterbelt will contain species, which act as windbreakers so that the

environment within the mine is contained.

Diseased and dead plants will be uprooted and replaced by fresh saplings.

Regular monitoring on survival rate and remedial action will be done in an

organized and planned manner.

4.5 Environmental Monitoring program

The survey of air pollution comprises of the following monitoring aspects;

i. Ambient air quality survey

ii. Noise Level Monitoring

10

Ambient air quality and noise level Monitoring will be carried out at minimum three

stations, one station within mine site and two stations nearby residential areas out- side

the mine. Parameters like suspended particulate matter, sulphur dioxide, oxides of

nitrogen carbon monoxide and lead will be monitored. The frequency of monitoring is

preferably once in three months on 24 hour basis. The samples will be collected in

accordance with the procedures given by CPCB.

4.6 Occupational health and safety

Health and safety aspects of the mine will be taken care off as per the World Bank (WB)

guidelines on open pit mining. The guidelines provide the detailed information on the

aspects that are required to be taken into account for maintaining proper health and safety

issues. The workers continuously exposed to dust will be provided with some protective

devices like dust mask to prevent respiratory disorders. The workers continuously

exposed to a high noise will be provided with ear muffs/ earplugs. Green belt in and

around the mining area will be developed to attenuate noise and dust impact. The blasting

carried out in the mine area will be carefully planned and executed under the supervision

of a responsible officer, to avoid any accidents. Drinking water supply for the employees

will be provided by the project authority. The standard of the drinking water will be per

WHO guidelines.

Periodical training programs to inform the employees about their task, associated risk,

and safe working practices will be undertaken. Training will also include information on

accident prevention, proper control and maintenance of equipment and safe material

handling practices.

A regular monitoring of the Occupational Health and Safety will reduce the chances of

accidents in the mine. Records of job related accidents and illness should be maintained.

This information will be reviewed and evaluated to improve the effectiveness of

Environmental Health and Safety programs.

11

4.7 Other management aspects

Records will be maintained for the analysis of ambient air quality and noise levels. These

records are not only required for the perusal of the Pollution Control Board authorities.

The management will maintain the records as per the hazardous waste regulations and

EPA regulations and apply for the annual consents for air and water, and renewal of

authorization for the storage of hazardous waste as per the Hazardous Waste (Handling &

Management) Rules, 1989. The records of hazardous waste manifest will be maintained.

The format of the same is enclosed in appendix.

The mine shall obtain the consent for operation (CFO) as required under section 25/26 of

the Water act, 1974 and under section 21/22 of Air Act, 1981, before trial production and

commissioning from the State Pollution Control Board. The CFO will be renewed each

year by the management. The mine will submit environmental statement every year

before September 30. The management ensures that it will comply with all the directions

and regulations issued by the Ministry of Environment and Forests, New Delhi, State and

Centre Pollution Control Boards.

The Consent for Establishment & Consent for Operation will be displayed in a

conspicuous location for reference to the inspecting authorities of different departments.

Conclusions

The Building Stone & Road Metal has major importers in Indian market. In

contrast to most of the other mines, the mining activities are very limited as

indicated by the area of the mine and mining process. The negative impacts

on air, noise, water can be minimized by the suggested mitigation measures.

Most of these impacts are temporary and short term. The proposed land is

not a forest land. No solid waste generation is found because total excavated

material will be used. No toxic or hazardous waste is present either in waste

or in mineral. With given Environmental Management Plan all the pollutants

will be kept within the prescribed limits.
